Four objects are situated along the y axis as follows: a 2.06-kg object is at +3.08 m, a 2.99-kg object is at +2.60 m, a 2.53-kg object is at the origin, and a 4.07-kg object is at -0.490 m. Where is the center of mass of these objects?

Ycm = 2.34m

Explanation:

See attachment below please.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

double the distance = divide strength by 4
